SPECIF1CATION forming part of Letters Patent No. 491,663, dated February14, 1893. Application led June 6, 1892. Serial No. 435,673. (No modali)To all whom t 11mg concern.-

Be it known that we, CHARLES PYLE and JOSEPH PYLE, citizens of theUnited States, residing at Lebanon, in the county of St. Clair and Stateof Illinois, have invented a new and useful Vindniill, of which thefollowing is a specification.

The invention relates to improvements in wind mills.

The object of the present invention is to simplify and improve theconstruction of wind mills, to equalize the strain and to enable them tobe readily controlled.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective view of a wind millconstructedin accordance with this invention. Fig. 2 is a verticalsectional view. Fig. 3 is a horizontal sectional view on line m of Fig.2. Fig. et is a similar view on line y, y.

Like numerals of reference indicate correspondin g parts in all thefigures of the drawings. y i

1 designates a tower in which is journaled a vertically disposedrotating frame 2 provided at its upper end with suitable bearings inwhich is journaled a shaft 3 carrying a centrally arranged wind wheel 4,which is supported at both sides thereby greatly equalizing the strain,and enabling the vertical frame 2 to rotate freely without friction. Therotating frame 2 is composed of four corner rods 5 bent outwardintermediate of their ends at 6 and connected by a rectangular frameformed by horizontal bars or rods 7 which have their ends secured to thecorner rods by couplings 8, and which carry intermediate their endsanti-friction rollers 9 which are arranged to bear against the walls ofa circular opening 10 of the top 11 of the tower, whereby the frame 2 isenabled to rotate freely. The lower ends of the corner rods areconnected by a circular plate 12 and is provided with a dependingjournal 13 which is arranged in a conical bearing 14 of a tube 15, andwhich is approximately conical to conform to the bearing and to enablethe bearing of the frame 2 to be without friction. The journal 13 isprovided with an annular groove 16 which is engaged by horizontal screws17 of a sleeve 18 secured to the upper end of the tube 15 and preventingthe journal rising from the conical bearing of the tube 15. The upperend of the bulged corner rods are connected by horizontal top pieces 19,and two of the corner rods support a horizontal vane bar 2O to the outerends of which are attached vanes 21 and 22 composed of blades secured tobars 23 and 24, the former of which has its inner end pivoted in abifurcation of the vane bar, thereby hinging the vane. The blade of thevane 21 is rigidly secured to the vane rod 23; and the blade of the vane22 is provided with bearings 25 in which the vane rod 21 is journaled,whereby the vane 22 may turn on the rod to allow the wheel to swing outof the wind, or partially so. The vane 22 is held in a vertical positionbya weight 26, and when the wind increases in force the vane is turnedby it against the action of the weight. The vane 21 is the main vane,and is hinged, and is adapted to be arranged at an angle of forty-fivedegrees to the wheel to hold the latter into the wind, and to be turnedparallel or in align with the wind wheel, to throw the latter out of thewind. The vane 22 is a supplemental one, and extends from the Vane barat an angle to the wheel.

The vanes are controlled by horizontal levers 27, which are fulcruinedat one side of the frame and have their ends at the opposite side of theframe connected by a cross-bar 2S to which is attached a rope 29 or thelike, which extends from the parallel levers 27 to the base of thetower. The parallel levers 27 are provided intermediate their ends withrollers 30 which are arranged on the inner faces of the levers, andwhich bear upon the upper face of a ring 31 to depress the ring and toallow the ring which is carried by the ver tical frame 2J to rotatewithout friction. The ring is provided with diametrically arranged bars32 to which are attached wires 33,Which are connected with a wire 34extending to an arm 36 of a bell-crank lever 37. The bell crank lever isT-shaped, and has the said IOC arm 36, which is arranged at right anglesto the arms 38 and 39, and extends horizontally and adapted to be drawndown by the wire 33. The vertical arms 38 and 39 are connected by rods40 and 41 with levers 42 and 43 which are fulcrumed intermediate theirends on the vane bar. The levers 42 and 43 are slightly curved at oneend; the lever 42 has its curved end arranged below the vane bar andadapted to engage the vane 22 below the vane bar 24 to lturn the vane toa horizontal position and lift the weight; and the lever 43 has itscurved end arranged above the vane bar and connected bya rod 44 with avane 2l, and adapted to turn the vane to hold the wind wheel into thewind, and to throw the same out of the wind. The upper connecting bar 4lextends from the arm 38 of the T-shaped leverto the upper end of thelever 42, and the lower connecting rod 4l extends from the arm 39 to anintermediate point of the lever 42. The lower connecting rod 40 connectsthe lower end ot' thelever 43 with the arm 39, and the upper connectingrod extends from an intermediate point of the lever 43 to the arm 38. Bythis arrangement the main vane, and the supplemental vane aresimultaneouslyr operated by means of the parallel levers. The shaft 3carries disks 45, which are arranged at the ends of the shaft and areprovided with wrist pins; and motion from the shaft is communicated to apump rod 46 by a pair of pitmen rods 47, which have their upper endsconnected to the wrist pins of the disks 45, and their lower endsattached tov outwardly extending arms 4SY of a ring 49 arranged on thetube. l5, and connected with the pump rod by transverse pins 50 arrangedin vertical slots of the tube 15, and disposed above and below the ring49. The ring is connected by a rod 5l with the pump rod 46, and the tubeis provided with an annular flange 52 which is secured to a horizontalboard ot' the tower.

It will be seen that the upper ends of the corner rod of the rotatingframe are connected by the top pieces and for-m two sidesbetween whichthe wind wheel rotates, and that the wind wheel is supported at bothsides, thereby equalizing the strain and greatly facilitating theoperation of the wind mill.

What we claim is l. In a wind mill, the combination of a tower, avertical frame rotatively mounted therein, a wind wheel mounted on theframe, a vane bar secured to the frame and arranged parallel with thewind wheel, a horizontally swinging main vane hinged at one end of thevane bar, a supplemental vane journaled at the other end of said bar,and means for controlling the vanes,substantially as described.

2. In a wind mill, the combination of a tower, a vertical framerotatively mounted therein, a wind wheel centrally arranged at the topof the frame, a vane bar secured to the vertical frame and arrangedparallel with the wheel, a main vane hinged at one end of the vane bar,a supplemental vane journaled at the other end of the vane bar andprovided with a depending weight, the curved levers fulcrumed on thevane bar and extending above and below the same, one of the levers beingarrranged to engage the supplemental vane and the other lever beingconnected with the main vane, a T-shaped lever fulcrumed on the vane-barand connected by rods with the curved lever, and means for connectingthe T-shaped lever with the base of the tower, substantially asdescribed.

3. In a wind mill, the combination ot' a tower. a vertical framerotatively mounted therein, a wind wheel arranged at the upper end ofthe frame, a Vane bar secured to the frame and Varranged longitudinallyof the wind wheel, a main vane hinged to one end of the vane bar, asupplemental vane journaled at the other end of the vane bar, leversfnlcrumed on the vane bar andadapted to turn the Vanes, a ring arrangedon the lower p0rtion ot the vertical frame and connected with saidlevers, and parallel levers each having one end fulcrumed on thetowerand provided intermediate its ends with an anti-friction rollerarranged on the ring and having its other end connected with a base ofthe tower, substantially as described.

4. In a wind mill, the combination of a tower, a vertical frame taperingfrom its middle to its end and rotatively mounted in the tower andcarrying a wind wheel, a tube pro- Vided with a conical bearing at itsupper end and having a securing llange at its lower end, a conicaljournal depending from the bottom of the vertical frame, and fitting inthe conical bearing and providedwith an annular groove, and a sleevesecured to the upper end of the tube and receiving the journal andprovided with screws arranged in said annular groove, substantially asand for the purpose described.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
